SECTION 6: MAINTAINING YOUR SNOW THROWER
WARNING: Before servicing, repairing or
inspecting, disengage all clutch levers and
stop engine. Wait until all moving parts have
come to a complete stop. Disconnect spark
plug wire and ground it against the engine to
prevent unintended starting.

Lubrication

Engine
•Refer to the engine manual for maintenance
procedures and instructions.
WARNING: When following instructions in
the engine manual for draining oil, be sure to
protect frame to avoid oil dripping onto
transmission parts.
Gear Shaft
•Lubricate the gear shaft with a good all-weather
multi-purpose light grease at least once a season or
after every 25 hours of operation.
Gear Case
•The auger gearbox has been filled with grease at
the factory. If disassembled for repairs, lubricate
with 1-1/2 ounces of grease (part no. 737-0168).
IMPORTANT:
Do not overfill the gear case. Damage to
the seals could result. Be sure the vent plug is free of
grease in order to relieve pressure.
Auger Shaft
•At least once a season, remove shear bolts on
auger shaft. Oil or spray lubricant inside shaft. Also
lubricate the auger bearings at least once a season.
See Figure 11.
Chute Directional Control
•The worm gear on the chute directional control
should be greased with multipurpose automotive
grease.
IMPORTANT:
Keep all grease and oil off friction wheel
and drive plate.
